To HAL when', it 'ma/y omi/own:

Be it known that I, JAMES S. COCHRAN, n citizen or the United States, residing in the city and county of Philadelphia, Stute of Pennsylvania, have invented n new and usevful Cellulose, of' which tho following is a, specification.

My invention Consists of it new process orl method oi utilizing the fuzz nl' cotton-seed hulls to produce a Cellulose which is useful for the manufacture of guncotton or other explosives, artilieiiil silk, (Sie.

T he iigure represents a vertical section of a. device that may he employed in carrying out my invention, and in Whieh- A designates n Grinding or attrition device of :my suitable orm, and B designates fa. chestwhieli is in nornrnunieation with the outlet of the onse of seid device.

C designates an agitator within said chest, and I) designates n sieve or screen in the chest below said ngitator. .Lending into said chest is the pi e of n. blower or :in nirhlast E, the same loving oullets which nre directed toward seid sieve nud guarded hy gauze or other suiinhle materiel. Below sind sereen in the chest is a, conveyor l", ifind above the saune is the chute (i, which is in cominnnieetion wil h the interior oi said chest und extends outside of the saine.

l Yfind that nlter cotton-smid isdivested o'lf :ill stnphihensueh :is not-ton and lint, ther-o renniins on the hull e non-stsiple netnre of the order of fuzz which of itself possesses Valuable qualities, 'l Subject the lmll so iivested to grindingor attrition or other ine chemie-nl nwiins, suoh ns hy the device A, whereby seid fuzz is diseonnoeted from the hull in pore nud nnvhnnged ronditon and then suhjoi'i tho hull und fuzz to nn nir-lilnst, sity in the chest Ii, sity hy the (levier: lil, thun svp-imi ing the fuzz from. the hull, lenving the former by itself, Without admixture, the sinne then being blown or drawn into tho chute G, by which it is directed elsewhere. The bran or hull roper, being lie-wier than the fuzz, drops tlirough the sieve I) below the seme, from whence it may be removed by the conveyor F.

I am aware tluit it has heen proposed to Subject oottoxbseed to solvents or other ehemieal aotionfto remove the Jfuzz from the hull, which practically destroys the same as fuzz; but in my ense I reelnim said substance from the hull in naturel condition, producing a commercial commodity for various purposes.

vIn some enses l bleach the fuzz, and thus form a veilulose oi' low grade which is admirnbly adapted for the manufacture of' guneotton or other explosive.

Having thus doscri hed my invention, whnt I olnini es new, sind desire Vto secure by Letters Pitti-nt, iss# Y 1. The method of making cellulose from thofnzz oi eotton-seed hull consisting in first removing,r nll ol` the stnple iher end lint from the seed und then mechanically roehiiming the fuzz from the hull in pure :ind unchanged condition.

2. The method of innkiug cellulose from the fuzz o1' nutten-semi indi consisting in iirst removing nil of the stnple liber anni lint from the seed, then m'vf-lnmimtlly reclaiming.: tinK fuzz from the im!! in pure nml nnvlmngi-d condition and next hlenehing snid fuzz.-

3. The method oll removing fuzz from cotton-seed hulls consisting in removing snid fnzziirst hy grindilngr und nitrition sind next hy on nir-lilnst whereby thei l'nzz is preserved innot its suoli und without zuhnixtni'e.
